The Autel 12+8 adapter is an essential tool for diagnosing and servicing late-model Chrysler, Dodge, Jeep, Ram, Fiat, and Alfa Romeo vehicles. These vehicles utilize a Security Gateway Module (SGM) that restricts access for aftermarket scan tools, often limiting functionality to only reading Diagnostic Trouble Codes (DTCs) and viewing basic data. The Autel 12+8 adapter bypasses the SGM, enabling full diagnostic capabilities with compatible Autel MaxiSys scanners.
Breaking Through the Security Gateway Module
Introduced in 2018 and newer FCA vehicles, the SGM acts as a firewall, preventing unauthorized access to the vehicle’s critical systems. Without the Autel 12+8 adapter, technicians using Autel scanners might encounter a “DEVICE UNABLE TO COMMUNICATE WITH THE CONTROL UNIT” message. The SGM’s location varies by model but is commonly found in the passenger-side kick panel, near the glove box, or behind the radio.
Compatibility and Functionality with Autel MaxiSys Scanners
The Autel 12+8 adapter connects directly to the Autel MaxiSys VCI and is compatible with a range of Autel MaxiSys scanners, including the MS906BT, MS906S, MS908, MS908S, MS908S Pro, and MaxiSys Elite. This adapter unlocks critical functionalities, allowing technicians to:
- Read and Clear Codes: Diagnose and resolve issues by accessing and clearing DTCs.
- Perform Active Tests: Initiate various vehicle components to pinpoint malfunctions.
- View Live Data: Monitor real-time sensor data for accurate diagnostics.
- Perform TPMS OBDII Relearn: Program new TPMS sensors efficiently.
- Coding and Adaptation: Configure vehicle modules to specific settings.
- ADAS Calibrations: Perform advanced driver-assistance system calibrations with MaxiSys ADAS software.
